That's a good idea, Dan.   

Agree with suggested wording, except 2nd sentence which somewhat
weakens it again.  May I tap on your wordings to suggest:

[R 5]  XML names must start with a letter (a to z or A to Z) optionally
followed by any number of letters or digits (0 to 9, a to z, and A to Z).
Other characters not described here, such as punctuations, periods,
spaces, or other separators MUST NOT appear in XML names.
As a regular expression this is represented as:  [a-zA-Z][a-zA-Z0-9]*
